Question

If a part of a chromosome gets separated and reattached in reverse position to the same chromosome, the mutation is called

• A. Inversion
• B. Transversion
• C. Translocation
• D. Gene mutation

Answer 1

The correct option is A Inversion

1) An inversion is a chromosome rearrangement in which a segment of a chromosome is reversed end to end.

2) Transversion refers to a point mutation in deoxyribonucleic acid (DNA), where a single (two ring) purine is changed for a (one ring) pyrimidine, or vice versa.

3) Translocation is a phenomenon where the chromosomal segment is moved from one position to another, either within the same chromosome or to another chromosome.

4) A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people.

So, the correct answer is 'Inversion'.
